Temporary Strainer

Please pay more attention to the viscosity flow rate, corrosiveness, temperature, and pressure drop of your liquid before you select.

To suit your existing system without any deviation, our temporary strainer dimensions are optional in actual manufacturing. You can refer to our standard technical data to choose from, or send us your independent sizes to custom.

Design Requirements

1. If a strainer cannot withstand high temperatures or differential pressures, it could come apart and cause damage to equipment.

2. The expected pressure drop across the strainer should not cause the downstream operating pressure to fall below the minimum required pressure of the line e.g. NPSH for a pump.

3. The perforations of the strainer should be slightly smaller than the smallest piece of debris that is expected to flow through it.

4. If the perforations are too small, a high pressure drop could develop across the strainer and cause it to fail.

Frequently Asked Questions (FAQ)

Q1: What is a pipeline strainer, and how does it differ from a pipeline filter?

A pipeline strainer is a protective component installed inline in a pipeline to remove large debris and particles before they reach downstream equipment. Unlike fine filtration, a strainer typically handles coarse solids and protects pumps, valves, and sensitive filtration stages. In some systems, the strainer functions as the first stage of the pipeline filtration system, whereas a pipeline filter provides finer particulate removal further downstream.

Q2: Can this temporary strainer be used as part of an inline pipeline filter setup?

Yes. Though the product is called a temporary strainer, it can be installed inline within the pipeline (i.e., as an inline pipeline filter) during start-up, commissioning, or when your permanent filtration system is offline. It provides interim protection in the pipeline filtration system by catching debris before it damages equipment or clogs finer filters.

Q3: In what situations is a temporary strainer useful in a pipeline filtration system?

During pipeline start-up or flushing, when construction debris or weld slag may be present

When bypassing or servicing the permanent inline pipeline filter

In systems with minimal solid loading, where continuous fine filtration is not yet installed

As a safeguard in emergency or transient states of the pipeline filtration process

Q4: How do I select the right size or mesh for a pipeline strainer?

Choose a straining mesh slightly smaller than the smallest debris expected in your fluid stream

Avoid making the perforations too fine, or the pressure drop will rise beyond acceptable levels

Ensure the open area of the strainer (relative to pipe cross-section) is sufficient (typical designs may support 100% to 300% open area)

Consider fluid viscosity, corrosiveness, pressure, and temperature when sizing

These design considerations are essential for effective pipeline filtration and optimal performance.

Q5: What's the recommended orientation for a conical pipeline strainer (cone facing upstream or downstream)?

If the cone faces downstream (i.e., the tip downstream), debris collects inside the cone tip—this makes debris removal easier, but the cone tip must be strong enough to withstand stress

If the cone faces upstream, debris accumulates toward the outer side, and plugging tends to occur from the outside in, which is safer under heavy loads

The choice depends on your system layout, ease of maintenance, and mechanical strength requirements.

Q6: How does a temporary strainer help protect the pipeline filtration system?

By capturing larger particles before they reach sensitive filtration stages, pumps, or valves, the temporary strainer acts as a first-line defense. This reduces the load on downstream filters, extends their service life, and prevents blockages or damage in your inline pipeline filter or other pipeline filtration components.

Q7: Can this temporary strainer be retrofitted into an existing pipeline filtration system?

Yes. We offer custom sizes and configurations, allowing the strainer to be seamlessly integrated into your existing pipeline or inline pipeline filter system without major deviations. You can provide your dimensions or use our standard technical data for sizing.

Q8: What materials and mesh options are available for pipeline strainers?

Our temporary strainers are typically constructed from stainless steel (e.g., SS304, SS316), but other corrosion-resistant alloys (e.g. Monel) may also be available. Standard mesh liners include 10, 20, 30, 40, 60, 80, and 100 mesh. We can also add support mesh or reinforcement frames to enhance strength for challenging pipeline filtration environments.

Q9: What is the expected pressure drop across this pipeline filter/strainer?

The pressure drop depends on mesh size, flow rate, differential loading, and the properties of the fluid. In designing your pipeline filtration system, ensure the pressure drop across the strainer does not drop the downstream pressure below critical levels (for instance, NPSH requirements for a pump). If the drop is excessive, consider using a coarser mesh or a design with a larger open area.

Q10: How do I maintain or clean the pipeline strainer?

Remove trapped debris periodically (depending on loading)

Choose a design allowing easy removal or flushing access

Monitor differential pressure to signal when cleaning is needed

In some designs, a support frame or mesh backing increases mechanical safety during cleaning or handling
